Help Increase elasticity of a cloth without loosing its shape

[Poupi]

Hi !
I started playing with Obi Cloth a few days ago, and I'm trying to make some kind of jelly with a highly elastic feeling, like Elastic Man  . I can't find any settings that would help me to do that without loosing the original shape of my object by changing the Stretching Scale value on the Distance Constraints. I tried to mess around with some values in the code but nothing seems to work well, and often breaks the simulation.

Video capture with Stretching Scale to 0.2 : https://gfycat.com/NextSophisticatedDodo

I want to have the shape shown in the first video with the physics of the second one (without the condom shape   ). This is probably the only cloth I'll have in the scene so it's ok if I have to change some settings directly in the code that could affect the whole behavior of the engine.

Thanks for your insights !

Hi,

Cloth is by definition a surface only simulation. For it to not lose its shape, you'd need a volumetric simulation that considers the entire volume of the jelly (using tetrahedral meshes) or cluster based shape matching (which we are working on for a completely new asset). The result you're after is just not achievable with a cloth simulator, to simulate soft bodies like jelly you'd need a softbody simulator.
